We look at the division of 56305201 by 820 
The aim is to understand the frequency of 820 in 56305201.

Going ahead to step 1:
When dividing 5 by 820, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 820

On to step 2:
When dividing 56 by 820, we get 0 with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 56 leaves us with 56.
Take the next digit (3) from the dividend and append it to 56, then repeat: 563 / 820

Going ahead to step 3:
820 can be fit into 563 0 times, resulting in a remainder of 563.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 563 and we're left with 563.
Grab the next digit (0) from the dividend, add it to 563, then carry on: 5630 / 820

On to step 4:
When dividing 5630 by 820, we get 6 with a remainder of 710.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 4920 from 5630 leaves us with 710.
Take the next digit (5) from the dividend and append it to 710, then repeat: 7105 / 820

Step 5:
820 goes into 7105 8 times with a remainder of 545.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
If we take 6560 away from 7105, we end up with 545.
Take the next digit (2) from the dividend and append it to 545, then repeat: 5452 / 820

Advancing to step 6:
5452 divided by 820 is 6 with a remainder of 532.
Record the quotient 6 as the next digit in the result. 
Result so far: 686.0
The remainder is 532 after subtracting 4920 from 5452.
Take the next digit (0) from the dividend and append it to 532, then repeat: 5320 / 820

On to step 7:
If we divide 5320 by 820, we get 6 and a remainder of 400.
Put 6 as the next digit of the answer. 
Result so far: 6866.0
The remainder is 400 after subtracting 4920 from 5320.
Take the next digit (1) from the dividend and append it to 400, then repeat: 4001 / 820

Let's proceed to step 8:
If we divide 4001 by 820, we get 4 and a remainder of 721.
Write down 4 as next digit of the result. 
Result so far: 68664.0
Deduct 3280 from 4001 and we're left with 721.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7210, and continue the process.

Let's proceed to step 9:
820 goes into 7210 8 times with a remainder of 650.
The next digit of our result is 8. 
Result so far: 68664.8
Deduct 6560 from 7210 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Let's proceed to step 10:
6500 divided by 820 is 7 with a remainder of 760.
Use 7 as the next digit of our solution. 
Result so far: 68664.87
The remainder is 760 after subtracting 5740 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 11:
820 can be fit into 7600 9 times, resulting in a remainder of 220.
The next digit of our result is 9. 
Result so far: 68664.879
Subtract 7380 from 7600 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 12:
The number 820 fits into 2200 2 times, leaving a remainder of 560.
Record the quotient 2 as the next digit in the result. 
Result so far: 68664.8792
Deduct 1640 from 2200 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 13:
When dividing 5600 by 820, we get 6 with a remainder of 680.
Use 6 as the next digit of our solution. 
Result so far: 68664.87926
Subtract 4920 from 5600 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 14:
820 can be fit into 6800 8 times, resulting in a remainder of 240.
Put 8 as the next digit of the answer. 
Result so far: 68664.879268
The remainder is 240 after subtracting 6560 from 6800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 15:
If we divide 2400 by 820, we get 2 and a remainder of 760.
Use 2 as the next digit of our solution. 
Result so far: 68664.8792682
The remainder is 760 after subtracting 1640 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Advancing to step 16:
7600 divided by 820 is 9 with a remainder of 220.
The next digit of our result is 9. 
Result so far: 68664.87926829
Subtract 7380 from 7600 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final outcome is 68664.87926829, with a leftover of 2.2e-07.
